Al Handasia For Advanced Irrigation Systems

- The hose is manufactured from polyethylene treated with Swedish masterbatch dye, resistant to heat and humidity, suitable for various weather conditions.   - The hose's outer diameter is 16mm.   - The hose's thickness is no less than 0.90mm and up to 1.3mm.   - The roll is 400 linear meters.   - The hose has passed a 9 bar pressure test for 70 minutes.   - The carbon content in the hose is no less than 5%.   - The hose is guaranteed against manufacturing defects and comes with a warranty from 1 to 10 years.   - The roll weighs no less than 14.25 kg and up to 20 kg.   - The hose roll is laser-printed with the company name and warranty period and includes a product card showing the company name, trademark, diameter, thickness, and manufacturing details from the production line and year.   - The hose is certified with ISO quality standards.   - Warranties are available for 1 year, 2 years, 3 years, 4 years, 5 years, 7 years, and 10 years.

- DIN 8061-8062 / DIN 19534. Compliant with German international standards. UPVC pipes are manufactured from polyvinyl chloride (PVC) ES848-2008/1 and ES1717, and conform to Egyptian standards.   - These pipes are widely used in water conveyance and main irrigation networks due to their smooth inner surface, low coefficient of friction, and resistance to sediment buildup.   - They are durable, impact-resistant, and resistant to acids and alkalis. They also exhibit high resistance to high concentrations of soil salts.   - They are rust-proof, corrosion-resistant, and lightweight.   - They are electrically insulating, easy to maintain and install, and resistant to harsh weather conditions.   - Pipe length is 6 meters, including overlaps, or as per customer request.   - Each pipe has a rubber gasket for easy connection.   - Pipe color is gray, or as per customer request.

- Outer diameters: 32mm, 50mm, 63mm, 75mm. Withstands pressure of 6 bar. DIN 8072 / DO 4427 / ISO. Manufactured according to international standards.   - Highly flexible, making it suitable for use in many systems.   - Weight and thickness vary depending on the roll diameter and warranty.   - Roll length: 100 meters.   - Resistant to corrosion and chemicals, and withstands harsh weather conditions.   - The hose is highly flexible, suitable for underground use, and resistant to soil pressure. Lightweight, easy to handle and install, and features a smooth inner wall that prevents sediment buildup.

- The mastermind and control centers of modern irrigation networks. Their role extends beyond simply opening and closing the water supply; they also protect the network from bursts and regulate water flow to ensure equitable distribution to every plant.   The most prominent types of valves used in irrigation networks: Isolation & Control Valves: Used for complete opening and closing to control water flow or isolate specific areas. Gate Valve: Relies on a metal disc that moves vertically and is preferred for complete opening and closing (without throttling) of main lines. Butterfly Valve: Consists of a circular disc that rotates around a central axis. Common in large lines for space saving and ease of operation. Ball Valve: Contains a perforated ball that rotates 90 degrees for opening or closing. It is characterized by its tight and rapid closure.   Automatic Solenoid Valves: An essential component in modern (automatic) irrigation systems. It operates via an electrical signal from the irrigation programmer to open or close the water supply at specific times and intervals.   Protective and Network Valves: Designed to protect the irrigation network from damage and malfunctions: Check Valve: Allows water to flow in only one direction and prevents backflow, thus protecting pumps from damage and back pressure. Air Release Valve: Placed at the highest point in the network to automatically release accumulated air, preventing "water hammer" which can damage pipes. Wash/Flush Valve: Placed at the ends of network lines to flush out sediment and impurities. Pressure Regulating Valve: Reduces and regulates the high pressure coming from the source to match the required operating pressure for drippers and sprinklers.

- Sprinkler irrigation systems in Egypt rely on several main types, varying according to soil type, crop, and operating method. These types include: stationary sprinklers, rotary sprinklers, center pivot and cannon sprinklers, and mini sprinklers. The appropriate type is selected based on the required pressure and coverage area.   - Fixed spray heads have no moving parts; instead, they rely on propelling water through a nozzle to create a consistent spray pattern. They are very common in irrigating lawns, home gardens, and landscapes, as well as in some open-field crops.   - Rotary sprinklers rotate slowly to cover wider areas and are characterized by distributing water in the form of uniform droplets with a range of 7 to 15 meters. They are widely used in large farms and public gardens.   - Impact sprinklers rely on an impact arm to propel water over very long distances and are considered long-range sprinklers. They are suitable for large field crops and open areas due to their high wind resistance.   - Center Pivot Sprinklers: A fully automated system that rotates around a central point to cover vast areas. Widely used in modern agricultural reclamation projects.   - Mini-sprinklers and micro-jets provide low flow rates, small irrigation areas, and produce water droplets resembling mist or spray. They are excellent for irrigating orchards and greenhouses to conserve water.
